If you want to run everything coming in the next year at top settings, perfectly, I do not believe you can do it for $900. You'll be spending $500 at least on the graphics card alone. If you were to add a couple hundred more dollars to your estimate, you could probably get off fairly well (still wouldn't be "maxed"). I'd guess 1300 for the system alone.

Granted, you can still get a very good rig for 900, but I don't know if it will last as long as you'll want it too.

Oh, and you're going to want to add some sort of aftermarket cooling to your equipment list. And you may not need a soundcard.
